carrier-icon-refrigerant-HFC-R-410A
  • 1 circuit:
    • Models: 90 / 100 / 120 / 160 / 180 / 182
  • 2 circuits:
    • Models: 200 / 240 / 320 / 360 / 420 / 485 / 540 / 600

General description

  • Centrifugal fan (EC plug-fan also available in models 90 to 360) 
  • Refrigerant R-410A
  • Casing made of galvanized steel metal with polyester paint, white color RAL 7035
  • All units are tested and checked in the factory

Air circuit

  • Coil(s) with copper pipes and aluminum fins
  • Centrifugal fan(s) coupling by pulleys and belts
  • Reusable air filters, assembled on a frame
  • Condensate drain pan

Cooling circuit

  • Thermostatic expansion valve(s) with external equalization

Protections

  • Main door switch.

Outdoor environment

  • Corrosion
    • Coil with copper pipes and copper fins
    • INERA® coil with copper pipes and fins of an aluminum alloy, of high performance and great resistance to the corrosion
    • Coil with copper pipes and aluminum fins with polyurethane and Blygold® coating
    • Condensate drain pan in stainless steel.
  • Humidity
    • Stop-drop in the indoor air coil
    • Stop-drop in the outdoor air intake

Comfort / heating options

  • Hot water auxiliary coil, with three-way valve. Two options:
    • Nominal coil for heating in cooling-only units
    • Auxiliary coil for heating in heat pump units
  • Auxiliary electrical heaters, air flow controller included

Comfort / indoor air quality options

  • Filtration of the supply air
  • Filtration of the return air (with centrifugal return fan)

Safety

  • Soft starter of the supply and/or return centrifugal fans which prolongs the set time mainly aimed at installations with cloth ducts
  • Differential pressostat for the detection of clogged filters
  • Differential pressostat for control of air flow
  • Smoke detecting station in accordance with the NF S 61-961 standard
  • Refrigerant leak detector (with CARRIERrtc control)

Installation

  • Anti-vibration mounts made of rubber
  • Position of supply and/or return of the indoor unit air
  • Supply and/or return fan with high available pressure
  • Electronic plug-fan(s) in air supply (upon request)
  • Assemblies with mixing box for air renewal and freecooling

Free cooling

  • On units with mixing box, the free-cooling can be managed by the electronic control
  • Three options for the free-cooling management:
    • Thermal, with comparison of temperatures
    • Enthalpic, with comparison of enthalpies
    • Thermoenthalpic, with comparison of enthalpies and a correction for temperature
